Description:

The instances of this structure class are the representation of
SBML reactions.

A REACTION represents any transformation, transport or binding
process, typically a chemical reaction, that can change the amount
of one or more species. In SBML, a REACTION is defined primarily in
terms of the participating reactants and products (and their
corresponding stoichiometries), along with optional modifier
species, an optional kinetic law describing the rate at which the
reaction takes place, and optional parameters entering into the
kinetic law.

The accessors REACTION-REACTANTS, REACTION-PRODUCTS,
REACTION-MODIFIERS, REACTION-KINETIC-LAW, REACTION-REVERSIBLE-P, and
REACTION-FAST-P are used to extract and set the structure
fields.
